Question

我正在尝试在collalering工具栏下面创建一个recyclelerview，其中包含了在recyclerview中的cardview。如何克服在recyclerview内部充满cardview的重叠。它与折叠的工具栏图像重叠。

Answer 2

在你的第一个布局文件中，放置recylerview AppBarLayout的底部：

<button type="button" style="margin-bottom: 5px;" class="btn btn-danger btn-default btn-gray btn-primary btn-primary2 btn-success2 btn-warning btn-black btn-success btn_bottom_padding" data-toggle="modal" data-target="#myModal" data-bind="css: {'btn-gray': IsGray(), 'btn-danger': IsRed(),'btn-success':IsGreen(), 'btn-primary': IsBlue(),'btn-success2':IsLimegreen(), 'btn-primary2': IsSkyblue(),'btn-warning':IsOrange(),'btn-black': IsBlack(),'btn-default':IsWhite()},click:$root.GetClick">
   <span data-bind="text:ShortName()"></span>
   <span data-bind="visible: IsRed()" class="fa fa-exclamation-triangle"></span>
   @*<span data-bind="" class="fa fa-bolt"></span>*@
</button>

而不是：

 android:layout_below="@+id/app_bar_layout"

recyclerview中的Cardview与折叠工具栏重叠
